Research Review: Structural language in autistic spectrum disorder – characteristics and causes / Jill BOUCHER in Journal of Child Psychology and Psychiatry, 53-3 (March 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-3 (March 2012) . - p.219-233 Titre : Research Review: Structural language in autistic spectrum disorder – characteristics and causes Type de document : Texte imprimé et/ou numérique Auteurs : Jill BOUCHER, Auteur Année de publication : 2012 Article en page(s) : p.219-233 Langues : Anglais (eng) Mots-clés : Autistic spectrum disorder  language;social interaction  mindreading  sensory-perceptual abilities  specific language impairment  intelligence  memory Index. décimale : PER Périodiques Résumé : Background:  Structural language anomalies or impairments in autistic spectrum disorder (ASD) are theoretically and practically important, although underrecognised as such. This review aims to highlight the ubiquitousness of structural language anomalies and impairments in ASD, and to stimulate investigation of their immediate causes and implications for intervention. Method:  Studies of structural language in ASD are reviewed (based on a search of the literature and selected as meeting defined inclusion criteria), and explanatory hypotheses are discussed. Results:  Some individuals with ASD never acquire language. Amongst those who do, language abilities range from clinically normal (ALN) to various degrees of impairment (ALI). Developmental trajectories and individual profiles are diverse, and minority subgroups have been identified. Specifically: language is commonly but not always delayed and delayed early language is always characterised by impaired comprehension and odd utterances, and sometimes by deviant articulation and grammar. Nevertheless, by school age an ‘ASD-typical’ language profile emerges from group studies, with articulation and syntax least affected, and comprehension, semantics and certain facets of morphology most affected. Thus, even individuals with ALN have poor comprehension relative to expressive language; also semantic-processing anomalies and idiosyncratic word usage. It is argued that impaired socio-emotional-communicative relating, atypical sensory-perceptual processing, and uneven memory/learning abilities may underlie shared language anomalies across the spectrum; and that varying combinations of low nonverbal intelligence, semantic memory impairment and comorbidities including specific language impairment (SLI), hearing impairment, and certain medical syndromes underlie ALI and variation in individual profiles. Conclusions:  Structural language is universally affected in ASD, due to a complex of shared and unshared causal factors. There is an urgent need for more research especially into the characteristics and causes of clinically significant language impairments.

A longitudinal twin study on the association between ADHD symptoms and reading / Corina U. GREVEN in Journal of Child Psychology and Psychiatry, 53-3 (March 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-3 (March 2012) . - p.234-242 Titre : A longitudinal twin study on the association between ADHD symptoms and reading Type de document : Texte imprimé et/ou numérique Auteurs : Corina U.

However, the stability and change of these genetic influences and the predictive relationships underlying this association longitudinally remain unclear. Methods:  ADHD symptoms and reading were assessed as continuous dimensions in a UK general population sample of approximately 7,000 twin pairs. Parent ratings of ADHD symptoms and teacher ratings of reading were obtained at two ages: middle childhood (ages 7–8 years) and early adolescence (ages 11–12 years). Cross-lagged quantitative genetic analyses were applied. Results:  ADHD symptoms and reading significantly predicted each other over time. However, ADHD symptoms were a significantly stronger predictor of reading than vice versa. Inattentive and hyperactive-impulsive symptoms of ADHD both contributed to the prediction of reading, but inattentiveness was a significantly stronger predictor. Furthermore, ADHD symptoms and reading were highly heritable, and their association was primarily attributable to shared genetic influences. Despite notable genetic innovation for each trait, genetic factors involved in the association of ADHD symptoms and reading over time were highly stable. Conclusions:  ADHD symptoms may put children at increased risk for reading problems and vice versa. Moreover, enduring genetic mechanisms appear to be important in the association of ADHD symptoms and reading over time.

Gene by environment interactions influencing reading disability and the inattentive symptom dimension of attention deficit/hyperactivity disorder / Jenni ROSENBERG in Journal of Child Psychology and Psychiatry, 53-3 (March 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-3 (March 2012) . - p.243-251 Titre : Gene by environment interactions influencing reading disability and the inattentive symptom dimension of attention deficit/hyperactivity disorder Type de document : Texte imprimé et/ou numérique Auteurs : Jenni ROSENBERG, Auteur ; Bruce F.

However, previous research indicates that RD and ADHD enter into opposite gene by environment (G × E) interactions. Methods:  This study used behavioral genetic methods to replicate these opposite G × E interactions in a sample of same-sex monozygotic and dizygotic twin pairs from the Colorado Learning Disabilities Research Center (CLDRC; DeFries et al., 1997) and to test a genetic hypothesis for why these opposite interactions occur. Results:  We replicated opposite G × E interactions for RD (bioecological) and ADHD-I (diathesis-stress) with parental education in the same sample of participants. The genetic hypothesis for this opposite pattern of interactions is that only genes specific to each disorder enter into these opposite interactions, not the shared genes underlying their comorbidity. To test this hypothesis, we used single models with an exploratory three-way interaction, in which the G × E interactions for each disorder were moderated by comorbidity. Neither three-way interaction was significant. The heritability of RD did not vary as a function of parental education and ADHD-I. Similarly, the heritability of ADHD-I did not vary as a function of parental education and RD. Conclusions:  We documented opposite G × E interactions in RD and ADHD-I in the same overall twin sample, but the explanation for this apparent paradox remains unclear. Examining specific genes and more specific environmental factors may help resolve the paradox.

A prospective longitudinal study of children’s theory of mind and adolescent involvement in bullying / Sania SHAKOOR in Journal of Child Psychology and Psychiatry, 53-3 (March 2012)

It is important for healthy social relationships and thus may contribute towards children’s involvement in bullying. The present study investigated whether children involved in bullying during early adolescence had poor ToM in childhood. Method:  Participants were members of the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally representative sample of 2,232 children and their families. We visited families when children were 5, 7, 10 and 12 years. ToM was assessed when the children were 5 years using eight standardized tasks. Identification of those children who were involved in bullying as victims, bullies and bully-victims using mothers’, teachers’ and children’s reports was carried out when they were 12 years’ old. Results:  Poor ToM predicted becoming a victim (effect size, d = 0.26), bully (d = 0.25) or bully-victim (d = 0.44) in early adolescence. These associations remained for victims and bully-victims when child-specific (e.g. IQ) and family factors (e.g. child maltreatment) were controlled for. Emotional and behavioural problems during middle childhood did not modify the association between poor ToM and adolescent bullying experiences. Conclusion:  Identifying and supporting children with poor ToM early in life could help reduce their vulnerability for involvement in bullying and thus limit its adverse effects on mental health.

Affective prosody labeling in youths with bipolar disorder or severe mood dysregulation / Christen M. DEVENEY in Journal of Child Psychology and Psychiatry, 53-3 (March 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-3 (March 2012) . - p.262-270 Titre : Affective prosody labeling in youths with bipolar disorder or severe mood dysregulation Type de document : Texte imprimé et/ou numérique Auteurs : Christen M.

Little research focuses on the processing of emotional prosody, or tone of verbal speech, in clinical populations. Methods:  Using the Diagnostic Analysis of Nonverbal Accuracy, the current study examined whether youths with pediatric-onset bipolar disorder (BD) and/or those with chronic and severe irritability (i.e. the severe mood dysregulation phenotype) are impaired in their ability to identify the emotional prosody of a spoken sentence with neutral content. Results:  Youths with severe mood dysregulation (n = 67) performed more poorly than healthy comparison children (n = 57), even when the sample was limited to unmedicated patients. Medicated BD youths (n = 52) exhibited impairment relative to healthy comparison children. No interactions between group and emotion were observed, suggesting that emotional prosody labeling problems may represent a general deficit in chronically irritable youths and in medicated youths with BD. Conclusion:  In concert with previously documented facial emotion labeling deficits, difficulties ascertaining the correct emotional tone of a spoken sentence may contribute to emotion dysregulation in chronically irritable children, and possibly also in youths with BD.

The impact of this specifier on children diagnosed with CD should be considered. Methods:  A multi-site cross-sectional design with volunteers (n = 1136) in the third–seventh grades and 566 consecutive referrals (ages 5–18) to a community mental health center were used to estimate the prevalence rates of CD with and without the proposed specifier. In addition, the degree of emotional and behavioral (especially physical aggression) disturbance and level of impairment in youth with and without CD and with and without the specifier was evaluated. Results:  In the community sample, 10%–32% of those with CD and 2%–7% of those without CD met the callous–unemotional (CU) specifier threshold depending on informant. In the clinic-referred sample, 21%–50% of those with CD and 14%–32% without CD met the CU specifier threshold depending on informant. Those with CD and the specifier showed higher rates of aggression in both samples and higher rates of cruelty in the clinic-referred sample. Conclusions:  Results indicate between 10% and 50% of youth with CD would be designated with the proposed CU specifier. Those with CD and the specifier appear to be more severe on a number of indices, including aggression and cruelty.

Perceptions of aggressive conflicts and others’ distress in children with callous-unemotional traits: ‘I’ll show you who’s boss, even if you suffer and I get in trouble’ / Dustin A. PARDINI in Journal of Child Psychology and Psychiatry, 53-3 (March 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-3 (March 2012) . - p.283-291 Titre : Perceptions of aggressive conflicts and others’ distress in children with callous-unemotional traits: ‘I’ll show you who’s boss, even if you suffer and I get in trouble’ Type de document : Texte imprimé et/ou numérique Auteurs : Dustin A. PARDINI, Auteur ; Amy L. BYRD, Auteur Année de publication : 2012 Article en page(s) : p.283-291 Langues : Anglais (eng) Mots-clés : Callous-unemotional  psychopathy  cognition  aggression  empathy Index. décimale : PER Périodiques Résumé : Background:  Children with callous-unemotional (CU) traits may have a particularly malevolent view of social conflicts and a pervasive insensitivity to others’ distress. The current study examined whether children with CU traits have unique expectations and values regarding the consequences of aggressive conflicts and a ubiquitous lack of concern for others’ feelings independent of co-occurring aggression. Methods:  Participants were 96 (46 males, 50 females) children recruited from elementary schools within an urban city. Associations between CU traits and child reports of outcome expectancies/values following aggressive conflicts and facets of empathy were examined after controlling for aggression, academic abilities, and demographic covariates. Results:  Children with higher CU traits were less likely to expect that aggression would result in victim suffering and feelings of remorse. After controlling for co-occurring aggression, children with higher CU traits were more likely to expect that aggression would result in peer dominance, while children with higher levels of aggression were more likely to expect that attacking others would reduce their aversive behavior. Children with higher CU traits were less concerned that aggressive behavior would result in punishment, victim suffering, and feelings of remorse. Moreover, children with higher CU traits reported lower levels of empathetic concern and sadness in response to others’ distress outside of aggressive conflicts. Conclusions:  Children with CU traits tend to minimize the extent to which aggression causes victim suffering and openly acknowledge caring less about distress and suffering in others. They are less intimidated by the possibility of being punished for aggressive behavior and tend to view aggression as an effective means for dominating others. In sum, children with CU traits have a particularly malicious social schema that may be difficult to change using conventional treatment methods.

The current study examined whether children with CU traits have unique expectations and values regarding the consequences of aggressive conflicts and a ubiquitous lack of concern for others’ feelings independent of co-occurring aggression. Methods:  Participants were 96 (46 males, 50 females) children recruited from elementary schools within an urban city. Associations between CU traits and child reports of outcome expectancies/values following aggressive conflicts and facets of empathy were examined after controlling for aggression, academic abilities, and demographic covariates. Results:  Children with higher CU traits were less likely to expect that aggression would result in victim suffering and feelings of remorse. After controlling for co-occurring aggression, children with higher CU traits were more likely to expect that aggression would result in peer dominance, while children with higher levels of aggression were more likely to expect that attacking others would reduce their aversive behavior. Children with higher CU traits were less concerned that aggressive behavior would result in punishment, victim suffering, and feelings of remorse. Moreover, children with higher CU traits reported lower levels of empathetic concern and sadness in response to others’ distress outside of aggressive conflicts. Conclusions:  Children with CU traits tend to minimize the extent to which aggression causes victim suffering and openly acknowledge caring less about distress and suffering in others.

Hierarchical and correlated factor analytic models were compared separately in the ADHD and sibling samples, across three different instruments and across parent and teacher informants. Specific consideration was given to factorial invariance analyses across different ages and different countries in the ADHD sample. Method:  A sample of children and adolescents between 5 and 17 years of age with ADHD and their unselected siblings was assessed. Participants were recruited from seven European countries and Israel. ADHD symptom data came from a clinical interview with parents Parental Account of Childhood Symptoms and questionnaires from parents and teachers (Conners Parent and Teacher). Results:  A hierarchical general factor model with two specific factors best represented the structure of ADHD in both the ADHD and unselected sibling groups, and across informants and instruments. The model was robust and invariant with regard to age differences in the ADHD sample. The model was not strongly invariant across different national groups in the ADHD sample, likely reflecting severity differences across the different centers and not any substantial difference in the clinical presentation of ADHD. Conclusions:  The results replicate previous studies of a model with a unitary ADHD component and separable specific traits of inattention and hyperactivity/impulsivity. The unique contribution of this study was finding support for this model across a large developmental and multinational/multicultural sample and its invariance across ages.

Method:  The participants were 10,987 pupils in the final three years of their compulsory education in Iceland (ages 14–16 years). The participants completed questionnaires in class relating to anxiety, depression and antiestablishment attitudes, ADHD symptoms, smoking, alcohol consumption and illicit drug use. Results:  Of the total sample, 5.4% met screening criteria for ADHD. Smoking, alcohol and illicit drug use were significantly related to ADHD symptoms. In addition, the number of different illicit drugs consumed was significantly higher among the ADHD symptomatic than the nonsymptomatic participants, including the illicit use of sedatives. The main distinguishing illicit drug substances were lysergic acid diethylamide (odds ratio or OR = 8.0), cocaine (OR = 7.5), mushrooms (OR = 7.1) and amphetamines (OR = 6.5). Logistic multiple regressions showed that after controlling for gender and school grade, ADHD symptoms predicted smoking, alcohol use and illicit drug use independent of anxiety, depression and antiestablishment attitudes. In addition, poly-substance use was linearly and incrementally related to ADHD symptoms with a large effect size. Conclusions:  The findings underscore the vulnerability of young persons with ADHD symptoms to smoking, alcohol and illicit drug use, possibly as a means of self-medication, and emphasize a need for early identification and treatment to reduce the risk of escalation.

A novel early intervention for preschool depression: findings from a pilot randomized controlled trial / Joan L. LUBY in Journal of Child Psychology and Psychiatry, 53-3 (March 2012)

LUBY, Auteur ; Shannon LENZE, Auteur ; Rebecca TILLMAN, Auteur Année de publication : 2012 Article en page(s) : p.313-322 Langues : Anglais (eng) Mots-clés : Preschool depression  Parent–Child Interaction Therapy Index. décimale : PER Périodiques Résumé : Background:  Validation for depression in preschool children has been established; however, to date no empirical investigations of interventions for the early onset disorder have been conducted. Based on this and the modest efficacy of available treatments for childhood depression, the need for novel early interventions has been emphasized. Large effect sizes (ES) for preschool psychotherapies for several Axis I disorders suggest that earlier intervention in depression may also be promising. Therefore, a novel form of treatment for preschool depression, Parent–Child Interaction Therapy Emotion Development (PCIT-ED) was developed and tested. Methods:  A preliminary randomized controlled trial (RCT) was conducted comparing PCIT-ED to psycho-education in depressed 3- to 7-year-olds and their caregivers. A total of 54 patients met symptom criteria for DSM–IV major depressive disorder and were randomized, 19 patients completed the active treatment (n = 8 dropouts) and 10 completed psycho-education (n = 17 dropouts). Results:  Both groups showed significant improvement in several domains, with PCIT-ED showing significance in a greater number of domains. An intent-to-treat analysis suggested that PCIT-ED was significantly more effective than psycho-education on executive functioning (p = .011, ES = 0.12) and emotion recognition skills (p = .002, ES = 0.83). Conclusions:  The RCT proved feasible and suggests an individual control condition should be used in future trials to minimize differential dropout. These pilot data, although limited by power, suggest that PCIT-ED may be a promising early intervention for depression. Larger scale randomized controlled trials of PCIT-ED for depressed preschoolers are now warranted.

Longitudinal study of neurological soft signs in first-episode early-onset psychosis / María MAYORAL in Journal of Child Psychology and Psychiatry, 53-3 (March 2012)

The study of the progression of NSS during adolescence will provide valuable information about the role of NSS as endophenotypes or biomarkers and about brain development at a stage in which brain maturation has not yet been completed. Methods:  Neurological soft signs were assessed in a sample of 110 first episodes of early-onset psychosis (EOP) and 98 healthy children and adolescents at two different times in a 2-year follow-up period. Results:  Patients with EOP showed more NSS than controls both at baseline (p < .001) and the 2-year follow-up (p < .001). No differences were found in the number of signs among the different diagnostic subgroups (schizophrenia, bipolar disorder, and other psychoses). When we examined the changes in NSS over the follow-up, the reduction of NSS in the patients was greater than the controls for ‘Motor coordination’ (p = .032), ‘Others’ (p < .001), and ‘Total score’ (p < .001) of the NES. Conclusion:  Despite the greater reduction of NSS in patients than in controls along the follow-up, patients still have more neurological signs than healthy controls; therefore, these signs may be considered a trait marker. NSS do not seem to be specific to schizophrenia as they are present in different EOPs.
